Description

計量システム、在庫管理システム及び計量方法Weighing system, inventory management system and weighing method
　本開示は、一般に計量システム、在庫管理システム及び計量方法に関し、より詳細には計量装置と電子タグを併用して計量する計量システム、在庫管理システム及び計量方法に関する。 The present disclosure generally relates to a weighing system, an inventory management system and a weighing method, and more particularly to a weighing system, an inventory management system and a weighing method that weigh using a weighing device and an electronic tag in combination.
　従来、物品の入出庫管理システムが知られている（特許文献１参照）。 Conventionally, an article warehousing / delivery management system is known (see Patent Document 1).
　特許文献１に記載された物品入出庫管理システムでは、重量センサによって測定された、物品とそれを格納する未開封物品パッケージもしくは開封済み物品パッケージの総重量と、ＩＤリーダにより読み取られた、パッケージに取り付けられたＩＤタグおよび作業者が携行するＩＤタグの情報とを、記憶部に記憶されている各種情報と組み合わせる。そうすることで、物品の入出庫作業状況もしくは在庫状況の遅延無き把握と、計画と実績との整合性の詳細なチェックを実現し、必要な作業指示や警告を作業者や管理者に与え、作業の適正化を図る。 In the article entry / exit management system described in Patent Document 1, the total weight of the article and the unopened article package or the opened article package for storing the article measured by the weight sensor, and the package read by the ID reader. The attached ID tag and the information of the ID tag carried by the worker are combined with various information stored in the storage unit. By doing so, it is possible to grasp the warehousing / delivery work status or inventory status of goods without delay, to realize a detailed check of the consistency between the plan and the actual result, and to give necessary work instructions and warnings to the workers and managers. Optimize work.
　特許文献１は、物品貯蔵庫では、未開封物品パッケージと開封済みパッケージとの総重量を重量センサで計量する。このためには、大型でダイナミックレンジが広い重量センサが必要である一方、開封済みパッケージ内の個品の数を識別するには個別重量の１／２より十分小さい分解能が必要であり、高価な重量センサが必要となる。全体の重量から個数への変換に際して、箱や梱包資材の重量ばらつきが大きい場合や、個品の重量が軽くて総数が多い場合には正確な識別が困難になる。 In Patent Document 1, in the article storage, the total weight of the unopened article package and the opened package is measured by a weight sensor. This requires a large, wide dynamic range weight sensor, while requiring a resolution well less than half the individual weight to identify the number of individual items in an opened package, which is expensive. A weight sensor is required. When converting from the total weight to the number, accurate identification becomes difficult when the weight variation of the box or packaging material is large, or when the weight of each individual item is light and the total number is large.

Other than these embodiments and modifications, various changes can be made according to the design and the like as long as they do not deviate from the technical idea of the present disclosure.
　（実施形態１）
　以下、本実施形態に係る計量システム、在庫管理システム及び計量方法について、図１～図４を用いて説明する。 (Embodiment 1)
Hereinafter, the weighing system, the inventory management system, and the weighing method according to the present embodiment will be described with reference to FIGS. 1 to 4.
　（１）概要
　本実施形態の計量システム１は、図１に示すように、管理装置１０と、リーダ１３と、バラ荷物計量部としての計量装置１１と、を備えている。 (1) Outline As shown in FIG. 1, the weighing system 1 of the present embodiment includes a management device 10, a reader 13, and a weighing device 11 as a loose baggage weighing unit.
　計量システム１は、例えば、所定数の個品７０が外箱６０に収納され、入庫時の個品７０の数のままで保管されている１つ以上のまとめ荷物１５と、個品７０が任意数取り出し可能な状態となっている１つ以上のバラ荷物１６と、の管理に用いられる。 In the weighing system 1, for example, one or more packaged packages 15 in which a predetermined number of individual items 70 are stored in the outer box 60 and are stored in the same number as the number of individual items 70 at the time of warehousing, and the individual items 70 are optional. It is used for managing one or more loose packages 16 that are ready to be taken out.
　本実施形態では、外箱６０とは、箱に限らず、例えば、書類、トレイ、かご、通函等を含む。すなわち、本実施形態では、複数の個品７０を一括管理できるような態様で保管しているものを外箱と定義している。 In the present embodiment, the outer box 60 is not limited to the box, but includes, for example, documents, trays, baskets, boxes, and the like. That is, in the present embodiment, an outer box is defined as a box in which a plurality of individual items 70 are stored in such a manner that they can be collectively managed.
　計量システム１は、例えば、物流倉庫に設置される。管理装置１０は、例えば、物流（在庫）を管理するサーバである。また、リーダ１３は、例えば、ＲＦＩＤ（Radio Frequency Identification）リーダ、又はＲＦＩＤリーダ／ライタである。リーダ１３と、管理装置１０とは互いに通信可能に構成されている。 The weighing system 1 is installed in a distribution warehouse, for example. The management device 10 is, for example, a server that manages physical distribution (inventory). Further, the reader 13 is, for example, an RFID (Radio Frequency Identification) reader or an RFID reader / writer. The reader 13 and the management device 10 are configured to be able to communicate with each other.
　本実施形態では、計量システム１は、物流倉庫で管理されている１つ以上のまとめ荷物１５と１つ以上のバラ荷物１６とをそれぞれ計数管理し、まとめ荷物１５とバラ荷物１６との双方の在庫を管理する。本実施形態では、計量システム１は、外箱６０ごと、つまりまとめ荷物１５ごとにまとめ荷物用タグ１４をつけて計数する。各バラ荷物１６にはタグをつけずに、１つ以上のバラ荷物１６の全量（総量）を計量装置１１で計量し、計量結果を基に１つ以上のバラ荷物１６の総数を求める。計量システム１は、まとめ荷物１５とバラ荷物１６との総数を基に、１つ以上のまとめ荷物１５と１つ以上のバラ荷物１６との在庫を管理している。 In the present embodiment, the weighing system 1 counts and manages one or more packaged packages 15 and one or more packaged packages 16 managed in the distribution warehouse, respectively, and both the packaged packages 15 and the packaged packages 16 Manage inventory. In the present embodiment, the weighing system 1 attaches a package tag 14 to each outer box 60, that is, for each package 15, and counts. The total amount (total amount) of one or more loose packages 16 is weighed by the weighing device 11 without attaching a tag to each loose package 16, and the total number of one or more loose packages 16 is calculated based on the weighing result. The weighing system 1 manages the inventory of one or more packaged packages 15 and one or more packaged packages 16 based on the total number of the packaged packages 15 and the loose packages 16.
　１つ以上のまとめ荷物１５及び１つ以上のバラ荷物１６を保管する空間ＳＰ１には、１つ以上のまとめ荷物１５を保管するまとめ荷物保管領域Ａ２及び１つ以上のバラ荷物１６を保管するバラ荷物保管領域Ａ１が設けられている。バラ荷物保管領域Ａ１は、バラ荷物１６の個数に応じて大きさが可変である。 In the space SP1 for storing one or more packaged packages 15 and one or more loose packages 16, the packaged baggage storage area A2 for storing one or more packaged packages 15 and the roses for storing one or more loose packages 16 A luggage storage area A1 is provided. The size of the loose baggage storage area A1 is variable according to the number of loose baggage 16.
　各まとめ荷物１５には、所定数で個品７０が入っているので、外箱単位でつけられたタグの個数を計数し、外箱６０の個数と所定数を掛け合わせることで、まとめ荷物１５の総数であるまとめ荷物総数を計算することができる。本実施形態では、まとめ荷物用タグ１４はパッシブＲＦＩＤタグであるとし、リーダ１３はＲＦＩＤリーダ／ライタであるとする。 Since each package 15 contains a predetermined number of individual items 70, the number of tags attached to each outer box is counted, and the number of outer boxes 60 is multiplied by the predetermined number to obtain the package 15 It is possible to calculate the total number of packages, which is the total number of packages. In the present embodiment, the baggage tag 14 is a passive RFID tag, and the reader 13 is an RFID reader / writer.
　取得部２は、まとめ荷物用タグ１４が設けられたまとめ荷物１５のタグ情報を、リーダ１３を介して各まとめ荷物用タグから取得する。まとめ荷物用タグ１４の識別子をＲＦＩＤリーダ／ライタで読み取ると、ＲＦＩＤリーダ／ライタは、管理装置１０の通信部９に読み取ったタグ情報を送信する。ここで、タグ情報は、品番、製造日、ロット番号、商品特性等を含む。 The acquisition unit 2 acquires the tag information of the package 15 provided with the tag 14 for the package from each tag for the package via the reader 13. Summary When the identifier of the luggage tag 14 is read by the RFID reader / writer, the RFID reader / writer transmits the read tag information to the communication unit 9 of the management device 10. Here, the tag information includes a product number, a manufacturing date, a lot number, product characteristics, and the like.
　一方、バラ荷物１６については、計量システム１は、計量装置１１により、バラ荷物１６の全体の重量を測定する。ここで、個品７０の１個あたりの重量がわかっており、また、計量装置１１の分解能も適切なものであれば、全体の重量から個品７０の個数を算出することができる。 On the other hand, with respect to the loose baggage 16, the weighing system 1 measures the total weight of the loose baggage 16 by the weighing device 11. Here, if the weight of each individual item 70 is known and the resolution of the weighing device 11 is also appropriate, the number of individual items 70 can be calculated from the total weight.
　計量装置１１において、計量装置１１に載せる個品７０は高々外箱１個分であるので、重量を測定するのは、外箱６０の１個分以内の重量で済む。このため、全体の重量を測定する計量装置１１は、秤量の小さな計量装置１１で十分となる。秤量が小さくなると、相対的に測定分解能を高くできるので、個品７０の個数の割り出しには効果がある。つまり、計量システム１は、個品７０を計数するのに適切な手段でもって計量することができる利点がある。また、個品７０の測定は１箱以内とすることは、測定誤差の累積を抑制する利点もある。 In the measuring device 11, since the individual item 70 to be mounted on the measuring device 11 is at most one outer box, the weight can be measured within the weight of one outer box 60. Therefore, as the weighing device 11 for measuring the entire weight, a weighing device 11 having a small weighing is sufficient. When the weighing is small, the measurement resolution can be relatively increased, which is effective in determining the number of individual products 70. That is, the weighing system 1 has an advantage that the individual product 70 can be weighed by an appropriate means for counting. Further, the measurement of the individual product 70 within one box also has an advantage of suppressing the accumulation of measurement errors.
　（２）構成
　本実施形態の計量システム１の構成について説明する。本実施形態の計量システム１は、図１に示すように、管理装置１０と、リーダ１３と、計量装置１１と、バラ荷物用タグ１２と、を備えている。 (2) Configuration The configuration of the weighing system 1 of the present embodiment will be described. As shown in FIG. 1, the weighing system 1 of the present embodiment includes a management device 10, a reader 13, a weighing device 11, and a loose baggage tag 12.
　リーダ１３は、１つ以上のまとめ荷物１５についているまとめ荷物用タグ１４の識別子を読み取り、読み取ったタグの情報を管理装置１０に送信する。 The reader 13 reads the identifier of the package tag 14 attached to one or more package packages 15 and transmits the read tag information to the management device 10.
　計量装置１１は、本実施形態では秤であり、例えば、重量センサ、ロードセルである。なお、計量装置１１は、１つ以上のバラ荷物１６（個品７０）の総量を計量するので、バラ荷物計量部ともいえる。以下では、計量装置１１をバラ荷物計量部１１として説明する。バラ荷物計量部１１は、秤であり、１つ以上のバラ荷物１６の全体の重量を計量する。バラ荷物計量部１１は、図３に示すように、通信部１１１と、処理部１１２と、を備えている。処理部１１２は、１つ以上のバラ荷物１６の全体の重量を計量する。重量を計量するため、個品７０が軽量の場合であっても、個品７０の最大個数は外箱の入数以下に限られるため、総重量のばらつきが大きくはならない。 The weighing device 11 is a scale in this embodiment, for example, a weight sensor and a load cell. Since the weighing device 11 measures the total amount of one or more loose packages 16 (individual items 70), it can be said to be a loose package weighing unit. Hereinafter, the weighing device 11 will be described as a loose baggage weighing unit 11. The loose baggage weighing unit 11 is a scale and weighs the entire weight of one or more loose baggage 16. As shown in FIG. 3, the loose parcel weighing unit 11 includes a communication unit 111 and a processing unit 112. The processing unit 112 weighs the entire weight of one or more loose packages 16. Since the weight is measured, even if the individual product 70 is lightweight, the maximum number of the individual product 70 is limited to the number of pieces in the outer box or less, so that the variation in the total weight does not become large.
　通信部１１１は処理部１１２が計量した結果を有線接続等によりバラ荷物用タグ１２へと送信する。 The communication unit 111 transmits the result of weighing by the processing unit 112 to the loose baggage tag 12 by a wired connection or the like.
　ここで、バラ荷物計量部１１に付随するバラ荷物用タグ１２について説明する。 Here, the loose baggage tag 12 attached to the loose baggage measuring unit 11 will be described.

To do.
　本実施形態では、個品７０が任意数取り出し可能な状態となっている１つ以上のバラ荷物１６については、個品７０はタグを有していない。バラ荷物計量部１１にバラ荷物用タグ１２が取り付けられ、バラ荷物用タグ１２の識別子をリーダ１３が読み取る構成となっている。この場合には、バラ荷物計量部１１の計量の結果は、リーダ１３を介して管理装置１０へと送信される。 In the present embodiment, the individual item 70 does not have a tag for one or more loose packages 16 in which an arbitrary number of individual items 70 can be taken out. A loose baggage tag 12 is attached to the loose baggage measuring unit 11, and the reader 13 reads the identifier of the loose baggage tag 12. In this case, the weighing result of the loose baggage measuring unit 11 is transmitted to the management device 10 via the reader 13.
　バラ荷物用タグ１２は、通信部１２１と、制御部１２２と、記憶部１２３と、を備えている。バラ荷物用タグ１２は、例えばアクティブＲＦＩＤタグである。 The loose baggage tag 12 includes a communication unit 121, a control unit 122, and a storage unit 123. The loose baggage tag 12 is, for example, an active RFID tag.
　記憶部１２３は、バラ荷物計量部１１の計量の結果を、バラ荷物１６の品番データに対応付けて記憶する。記憶部１２３は制御部１２２の制御信号に応じて、計量の結果を制御部１２２及び通信部１２１を介して管理装置１０に送信する。 The storage unit 123 stores the measurement result of the loose baggage measuring unit 11 in association with the product number data of the loose baggage 16. The storage unit 123 transmits the measurement result to the management device 10 via the control unit 122 and the communication unit 121 in response to the control signal of the control unit 122.
　通信部１２１は、リーダ１３と通信を行う通信インターフェースを備えている。例えば、通信部１４１は、記憶部１２３が記憶する計量の結果を、リーダ１３を介して管理装置１０に送信する。 The communication unit 121 is provided with a communication interface that communicates with the reader 13. For example, the communication unit 141 transmits the measurement result stored in the storage unit 123 to the management device 10 via the reader 13.
　制御部１２２は、通信部１２１がリーダ１３と通信するタイミングを制御する。また、制御部１２２は記憶部１２３の計量の結果を通信部１２１に送信する。 The control unit 122 controls the timing at which the communication unit 121 communicates with the reader 13. Further, the control unit 122 transmits the measurement result of the storage unit 123 to the communication unit 121.
　管理装置１０は、制御部７と、表示部８と、通信部９と、管理部５０と、を備えている。 The management device 10 includes a control unit 7, a display unit 8, a communication unit 9, and a management unit 50.
　表示部８は、まとめ荷物総量及びバラ荷物総量のうち少なくとも一方を表示する。例えば、バラ荷物総量を表示する場合には、物流倉庫の作業者が視覚的に把握することができ、補充品の準備等に生かすことができる。本実施形態では、表示部８は、まとめ荷物総量及びバラ荷物総量の両方を表示する。 The display unit 8 displays at least one of the total amount of bulk packages and the total amount of loose packages. For example, when displaying the total amount of loose parcels, the worker of the distribution warehouse can visually grasp it, which can be utilized for the preparation of replenishment and the like. In the present embodiment, the display unit 8 displays both the total amount of bulk packages and the total amount of loose packages.
　通信部９は、リーダ１３と相互に通信する通信インターフェースを備えている。 The communication unit 9 is provided with a communication interface that communicates with the reader 13.
　制御部７は、取得部２と、まとめ荷物計数部３と、バラ荷物計数部４と、取出数量算出部５と、異常報知部６と、無効化処理部２１と、フィードバック部４３と、を備える。制御部７は、例えば、プロセッサ及びメモリを有するマイクロコンピュータを有している。そして、プロセッサがメモリに格納されているプログラムを実行することにより、マイクロコンピュータが制御部７として機能する。プロセッサが実行するプログラムは、ここではマイクロコンピュータのメモリに予め記録されているが、メモリーカード等の記録媒体に記録されて提供されてもよいし、インターネット等の電気通信回線を通じて提供されてもよい。 The control unit 7 includes an acquisition unit 2, a bulk package counting unit 3, a loose package counting unit 4, a take-out quantity calculation unit 5, an abnormality notification unit 6, an invalidation processing unit 21, and a feedback unit 43. Be prepared. The control unit 7 has, for example, a microcomputer having a processor and a memory. Then, when the processor executes the program stored in the memory, the microcomputer functions as the control unit 7. The program executed by the processor is recorded in advance in the memory of the microcomputer here, but may be recorded in a recording medium such as a memory card and provided, or may be provided through a telecommunication line such as the Internet. ..
　取得部２は、１つ以上のまとめ荷物１５から、対応するまとめ荷物用タグ１４に関連するタグ情報を、通信部９を介して取得する。取得部２は、管理装置１０の通信部９から、まとめ荷物１５のタグ情報を取得する。取得部２は、受け取ったデータをまとめ荷物計数部３及びバラ荷物計数部４に引き渡す。 The acquisition unit 2 acquires tag information related to the corresponding package bag tag 14 from one or more package packages 15 via the communication unit 9. The acquisition unit 2 acquires the tag information of the package 15 from the communication unit 9 of the management device 10. The acquisition unit 2 collects the received data and hands it over to the baggage counting unit 3 and the loose baggage counting unit 4.
　まとめ荷物計数部３は、１つ以上のまとめ荷物１５の各々から取得したタグ情報を用いて、１つ以上のまとめ荷物１５の総数であるまとめ荷物総数を求める。例えば、まとめ荷物計数部３は、外箱６０の所定数と、取得部２が取得したタグ情報の品番の個数と、を掛け合わせることにより、まとめ荷物総数を算出する。 The summary package counting unit 3 uses the tag information acquired from each of the one or more package 15s to obtain the total number of packages 15 which is the total number of one or more packages 15. For example, the packaged package counting unit 3 calculates the total number of packaged packages by multiplying the predetermined number of the outer boxes 60 and the number of product numbers of the tag information acquired by the acquisition unit 2.
　まとめ荷物計数部３は、求めたまとめ荷物総数を表示部８に出力して、まとめ荷物総数を表示部８に表示させる。 The packaged package counting unit 3 outputs the calculated total number of packaged packages to the display unit 8 and displays the total number of packaged packages on the display unit 8.
　バラ荷物計数部４は、バラ荷物計量部１１による計量の結果を取得部２から受け取り、１つ以上のバラ荷物１６の総数であるバラ荷物総数を求める。例えば、バラ荷物計数部４は、バラ荷物１個あたりの重量が記載されたデータベースと、バラ荷物全体の計量の結果から、バラ荷物１６の総数であるバラ荷物総数を算出することができる。 The loose parcel counting unit 4 receives the result of weighing by the loose parcel weighing unit 11 from the acquisition unit 2 and obtains the total number of loose parcels, which is the total number of one or more loose parcels 16. For example, the loose parcel counting unit 4 can calculate the total number of loose parcels, which is the total number of the parcels 16, from the database in which the weight per parcel is described and the result of weighing the entire parcel.
　バラ荷物計数部４は、バラ荷物全体の計量の結果から、バラ荷物１６の総数であるバラ荷物総数を算出する場合に、バラ荷物全体の計量の結果から、外箱及び副資材の重量を除いて、バラ荷物１６の１個あたりの重量で除算する。このとき、バラ荷物総数が整数値から所定以上乖離している場合には警報を発する。例えば、バラ荷物総数の値が整数値から±０．２５よりも大きくずれた場合に警報を発する。 When calculating the total number of loose packages, which is the total number of 16 packages, the loose package counting unit 4 excludes the weights of the outer box and auxiliary materials from the results of weighing the entire package. Then, divide by the weight of each piece of the loose baggage 16. At this time, if the total number of loose packages deviates from the integer value by a predetermined value or more, an alarm is issued. For example, an alarm is issued when the value of the total number of loose packages deviates from the integer value by more than ± 0.25.
　バラ荷物計数部４は、フィードバック部４３を更に備えている。フィードバック部４３は、バラ荷物計数部４が求めたバラ荷物総数がゼロである場合には、バラ荷物総数がゼロであることを知らせる。 The loose baggage counting unit 4 further includes a feedback unit 43. When the total number of loose packages obtained by the loose baggage counting unit 4 is zero, the feedback unit 43 notifies that the total number of loose packages is zero.
　バラ荷物計数部４は、求めたバラ荷物総数４２を表示部８に出力して、バラ荷物総数を表示部８に表示させる。 The loose baggage counting unit 4 outputs the obtained total number of loose packages 42 to the display unit 8 and displays the total number of loose packages on the display unit 8.
　取出数量算出部５は、個品をピッキングする作業時において、取り出した個品の数量である取出数量を算出する。 The take-out quantity calculation unit 5 calculates the take-out quantity, which is the quantity of the individual products taken out at the time of picking the individual products.
　まず、取出数量算出部５は、まとめ荷物１５及びバラ荷物１６を棚から取り出す前において、まとめ荷物計数部３が求めたまとめ荷物総数に、バラ荷物計数部４が求めたバラ荷物総数を加算して第１総数を算出する。 First, the take-out quantity calculation unit 5 adds the total number of loose packages calculated by the bulk package counting unit 4 to the total number of packages calculated by the package counting unit 3 before taking out the package 15 and the package 16 from the shelf. The first total number is calculated.
　次に、取出数量算出部５は、まとめ荷物１５及びバラ荷物１６を棚から取り出した後において、まとめ荷物計数部３が求めたまとめ荷物総数に、バラ荷物計数部４が求めたバラ荷物総数を加算して第２総数を算出する。 Next, after taking out the packaged packages 15 and the packaged packages 16 from the shelves, the take-out quantity calculation unit 5 adds the total number of packaged packages calculated by the packaged package counting unit 4 to the total number of packages calculated by the packaged package counting unit 3. Add up to calculate the second total number.
　取出数量算出部５は、第１総数と第２総数との差分の値から取出数量を計算する。 The withdrawal quantity calculation unit 5 calculates the withdrawal quantity from the value of the difference between the first total number and the second total number.
　異常報知部６は、取出数量算出部５が計算した取出数量が、作業者が予定していた取出予定数量と合致しない場合に、作業者に異常を報知する。例えば、作業者が携帯する端末に表示したり、警報音で知らせたりする。 The abnormality notification unit 6 notifies the worker of the abnormality when the withdrawal quantity calculated by the take-out quantity calculation unit 5 does not match the withdrawal planned quantity planned by the worker. For example, it may be displayed on a terminal carried by an operator or notified by an alarm sound.
　無効化処理部２１は、１つ以上のまとめ荷物１５のうち、一のまとめ荷物１５から少なくとも１つの個品が取り出された場合に、当該一のまとめ荷物１５に対応するまとめ荷物用タグ１４を無効化する処理をまとめ荷物用タグ１４に対して行う。ここで、無効化とは、まとめ荷物用タグ１４は外箱６０に貼着されているが、少なくとも１つ以上の個品が取り出され、まとめ荷物１５からバラ荷物１６へと扱いが変わることを意味している。 When at least one individual item is taken out from one package 15 among one or more package 15, the invalidation processing unit 21 attaches a package tag 14 corresponding to the one package 15. The process of invalidating is collectively performed on the baggage tag 14. Here, invalidation means that the bulk baggage tag 14 is attached to the outer box 60, but at least one or more individual items are taken out, and the handling is changed from the bulk baggage 15 to the loose baggage 16. Means.
　例えば、まとめ荷物１５から個品７０を取り出して、リーダ１３としてのハンディタイプのＲＦＩＤリーダ／ライタでまとめ荷物１５のタグの識別子を読み取ると、ＲＦＩＤリーダ／ライタが読み取ったタグ情報は、管理装置１０の無効化処理部２１に引き渡される。例えば、タグ情報の中に、まとめ荷物用タグ１４として、有効の場合には「１」、無効の場合には「０」となるような有効と無効とを識別する識別子を入れておき、適宜書き換えることで、無効化処理部２１は有効と無効とを切り替えることができる。例えば、まとめ荷物１５の外箱６０から１つ以上の個品７０を作業者が取り出した場合には、作業者は、リーダ１３に対して所定の操作を行う。このとき、計量システム１は、無効化処理を実行する。具体的には、無効化処理部２１は、有効なタグ情報を無効なタグ情報へと書き換え、書き換えられたタグ情報は通信部９を介してリーダ１３に送信される。リーダ１３は、無効のタグ情報を受け取ると、ＲＦＩＤリーダ／ライタはまとめ荷物１５のうち、個品を取り出したまとめ荷物用タグ１４に、無効のタグ情報を書き込む。上記により、無効のタグ情報が書き込まれたまとめ荷物用タグ１４が設けられたまとめ荷物１５の各個品は、バラ荷物１６として扱われる。 For example, when the individual item 70 is taken out from the packaged baggage 15 and the identifier of the tag of the packaged baggage 15 is read by the handy type RFID reader / writer as the reader 13, the tag information read by the RFID reader / writer is the management device 10. Is handed over to the invalidation processing unit 21 of. For example, in the tag information, an identifier that distinguishes between valid and invalid such that the tag 14 for bulk luggage is "1" when it is valid and "0" when it is invalid is appropriately inserted. By rewriting, the invalidation processing unit 21 can switch between valid and invalid. For example, when the worker takes out one or more individual items 70 from the outer box 60 of the bulk baggage 15, the worker performs a predetermined operation on the reader 13. At this time, the weighing system 1 executes the invalidation process. Specifically, the invalidation processing unit 21 rewrites the valid tag information into invalid tag information, and the rewritten tag information is transmitted to the reader 13 via the communication unit 9. When the reader 13 receives the invalid tag information, the RFID reader / writer writes the invalid tag information on the package bag tag 14 from which the individual items are taken out from the package bag 15. As described above, each individual item of the packaged package 15 provided with the packaged baggage tag 14 on which invalid tag information is written is treated as a loose package 16.
　ここでは、図２に示すまとめ荷物用タグ１４について説明する。まとめ荷物用タグ１４は、通信部１４１、制御部１４２及び記憶部１４３を備えている。 Here, the summary luggage tag 14 shown in FIG. 2 will be described. Summary The luggage tag 14 includes a communication unit 141, a control unit 142, and a storage unit 143.
　通信部１４１は、リーダ１３と通信を行うインターフェースを備えている。例えば、通信部１４１は、まとめ荷物用タグ１４に関連するタグ情報をリーダ１３に引き渡す。また、通信部１４１は、ライタ機能を有するリーダ１３からまとめ荷物用タグ１４の無効に関連するタグ情報をリーダ１３から受け取る。 The communication unit 141 is provided with an interface for communicating with the reader 13. For example, the communication unit 141 delivers the tag information related to the package baggage tag 14 to the reader 13. Further, the communication unit 141 receives tag information related to invalidation of the package baggage tag 14 from the reader 13 having a writer function.
　記憶部１４３は、まとめ荷物用タグ１４のタグ情報を記憶する。例えば、タグ情報は、まとめ荷物用タグ１４としての有効、無効に加えて、まとめ荷物１５の属性情報として、例えば、品番、製造日、ロット番号、商品特性を含む。タグ情報は、１つ以上のまとめ荷物１５のうち、対応するまとめ荷物１５で収納されている個品７０の総数を所定数として含んでもよい。また、まとめ荷物用タグ１４の各々は、１つ以上のまとめ荷物１５のうち、対応するまとめ荷物１５の属性に係る属性情報を記憶している。バラ荷物用タグ１２は、１つ以上のまとめ荷物１５のうちの１のまとめ荷物１５から少なくとも１つの個品７０が取り出された場合に、１のまとめ荷物１５のまとめ荷物用タグから属性情報を取得する。 The storage unit 143 stores the tag information of the bulk baggage tag 14. For example, the tag information includes, for example, a product number, a manufacturing date, a lot number, and a product characteristic as attribute information of the packaged package 15 in addition to being valid and invalid as the packaged package tag 14. The tag information may include the total number of individual items 70 stored in the corresponding package 15 among the one or more package 15 as a predetermined number. Further, each of the bundled baggage tags 14 stores the attribute information related to the attribute of the corresponding grouped baggage 15 among the one or more grouped baggage 15. When at least one individual item 70 is taken out from the packaged baggage 15 of one of the grouped packages 15 of one or more, the loose baggage tag 12 obtains attribute information from the packaged baggage tag of the packaged baggage 15. get.
　制御部１４２は、通信部１４１がリーダ１３と通信するタイミングを制御する。制御部１４２は、記憶部１４３のタグ情報を読み取り、通信部１４１に送信する。また、制御部１４２は、通信部１４１から無効に関するタグ情報を受信すると、記憶部１４３に無効に関するタグ情報を書き込む。 The control unit 142 controls the timing at which the communication unit 141 communicates with the reader 13. The control unit 142 reads the tag information of the storage unit 143 and transmits it to the communication unit 141. Further, when the control unit 142 receives the tag information regarding invalidity from the communication unit 141, the control unit 142 writes the tag information regarding invalidity in the storage unit 143.
　（３）動作
　ここでは、所定数の個品が外箱に収納され、入庫時の個数の数のままで保管されている１つ以上のまとめ荷物１５と、個品が任意数取り出し可能な状態となっている１つ以上のバラ荷物１６の管理に用いられる計量システム１及び計量方法について、図５を用いて説明する。 (3) Operation Here, a predetermined number of individual items are stored in the outer box, and one or more packaged packages 15 that are stored as the number at the time of warehousing and an arbitrary number of individual items can be taken out. The weighing system 1 and the weighing method used for managing one or more loose packages 16 are described with reference to FIG.
　１つ以上のまとめ荷物１５の各々にはまとめ荷物用タグ１４が設けられている。例えば、入荷してきた外箱にまとめ荷物用タグ１４が設けられてもよい。まとめ荷物用タグ１４は、例えば、個品で入荷してきたバラ荷物１６にはタグは設けない。 Each of one or more packaged packages 15 is provided with a packaged baggage tag 14. For example, the baggage tag 14 may be provided on the outer box that has arrived. As for the summary baggage tag 14, for example, no tag is provided for the loose baggage 16 that has arrived as an individual item.
　取得部２は、通信部９を介して、１つ以上のまとめ荷物１５の各々のタグ情報を取得する（ステップＳ１０）。 The acquisition unit 2 acquires the tag information of each of the one or more packaged packages 15 via the communication unit 9 (step S10).
　まとめ荷物計数部３は、例えば、品番データベースから得られる１箱あたりの個品７０の個数と、外箱６０の個数とを掛け合わせることにより、まとめ荷物１５の総数であるまとめ荷物総数を算出する（ステップＳ１１）。 The package counting unit 3 calculates the total number of packages, which is the total number of packages 15, by multiplying, for example, the number of individual items 70 per box obtained from the product number database and the number of outer boxes 60. (Step S11).
　次に、バラ荷物１６の計数方法について説明する。バラ荷物１６にはタグが設けられていないので、バラ荷物計量部１１は、具体的には計量装置である。バラ荷物計量部１１は、まとめ荷物計数部３によるまとめ荷物総数の計量方法とは異なる計量方法によって、１つ以上のバラ荷物１６の全体の計量を行う。 Next, the counting method of the loose baggage 16 will be described. Since the loose baggage 16 is not provided with a tag, the loose baggage measuring unit 11 is specifically a weighing device. The loose parcel weighing unit 11 weighs one or more loose parcels 16 as a whole by a weighing method different from the method of weighing the total number of parcels collected by the bulk parcel counting unit 3.
　バラ荷物計量部１１は、１つ以上のバラ荷物１６の全体の重量を計量する。バラ荷物１６は、バラ荷物保管領域Ａ１で保管されている。バラ荷物計量部１１は、バラ荷物保管領域Ａ１で保管されている１つ以上のバラ荷物１６を計量する。次に、通信部１１１は、計量の結果を管理装置１０の通信部９へと送信する（ステップＳ１２）。 The loose baggage weighing unit 11 weighs the entire weight of one or more loose baggage 16. The loose baggage 16 is stored in the loose baggage storage area A1. The loose baggage weighing unit 11 weighs one or more loose baggage 16 stored in the loose baggage storage area A1. Next, the communication unit 111 transmits the measurement result to the communication unit 9 of the management device 10 (step S12).
　バラ荷物計数部４は、通信部９を介して、バラ荷物計量部１１の計量の結果を取得する。バラ荷物計数部４は、取得した計量の結果を、バラ荷物１６（個品７９）の１個あたりの重量で割り算してバラ荷物総数を算出する（ステップＳ１３）。このとき、バラ荷物１６（個品７９）の１個あたりの重量は、あらかじめデータベースが準備されていてもよいし、又は計量の結果に品番が含まれていてもよい。 The loose parcel counting unit 4 acquires the weighing result of the loose parcel weighing unit 11 via the communication unit 9. The loose parcel counting unit 4 divides the acquired weighing result by the weight of each of the loose parcels 16 (individual items 79) to calculate the total number of loose parcels (step S13). At this time, a database may be prepared in advance for the weight of each piece of the loose baggage 16 (individual item 79), or the item number may be included in the measurement result.
　バラ荷物計数部４は、まとめ荷物計数部３の計数結果とバラ荷物計数部４の計数結果とを、加算することで、荷物総数を算出する（ステップＳ１４）。 The loose parcel counting unit 4 calculates the total number of parcels by adding the counting result of the bulk parcel counting unit 3 and the counting result of the loose parcel counting unit 4 (step S14).
　（４）利点
　本実施形態では、計量システム１は、まとめ荷物１５とバラ荷物１６とが混在する環境において、まとめ荷物１５はＲＦＩＤタグを用いて計数し、バラ荷物１６は計量装置１１でまとめて計量することにより、まとめ荷物１５とバラ荷物１６とを合わせて在庫管理できる。 (4) Advantages In the present embodiment, in the weighing system 1, in an environment where the packaged packages 15 and the packaged packages 16 are mixed, the packaged packages 15 are counted by using RFID tags, and the packaged packages 16 are grouped by the weighing device 11. By weighing, the inventory of the bulk package 15 and the loose package 16 can be managed together.
　本実施形態以外にも、例えば、外箱にＲＦＩＤタグをつけて個数を管理したり、個品全てにタグをつけて個数を管理したりする手法が考えられる。個品全てにタグをつけることができれば、うまく管理することができるが、タグのコストが高くなる、個品のサイズによっては取り付けられない、タグをつけると価値が減じてしまう、などの理由で、個品全てにタグをつけるのは現実的ではない。 In addition to the present embodiment, for example, a method of attaching an RFID tag to the outer box to manage the number of items, or attaching a tag to all individual items to manage the number of items can be considered. If you can tag all the individual items, you can manage them well, but the cost of the tag will be high, it will not be attached depending on the size of the individual item, and the value will be reduced if you attach the tag. , It is not realistic to tag all individual items.
　一方、本実施形態では、外箱６０（まとめ荷物１５）にまとめ荷物用タグ１４を設け、バラ荷物１６にはタグを設けていない。そのため、上記理由を解消できる。 On the other hand, in the present embodiment, the outer box 60 (collective luggage 15) is provided with the collective luggage tag 14, and the loose luggage 16 is not provided with the tag. Therefore, the above reason can be eliminated.
　本実施形態によると、計量システム１は、例えば、タグがつけられないような小さな個品にも適用可能である。 According to this embodiment, the weighing system 1 can be applied to, for example, small individual items that cannot be tagged.

It may be configured to be used.
　バラ荷物計量部１１は、バラ荷物１６を計量するだけではなく、外箱や梱包資材も同時に計量してもよい。この場合には、バラ荷物計量部１１は、例えば、秤の風袋機能を使用するのが簡便である。 The loose baggage weighing unit 11 may not only weigh the loose baggage 16 but also weigh the outer box and packing materials at the same time. In this case, it is convenient for the loose baggage measuring unit 11 to use, for example, the tare function of the scale.
　まとめ荷物１５のまとめ荷物用タグ１４に、外箱の中にある個品の数の情報をまとめ荷物用タグ１４は含んでいてもよい。例えば、まとめ荷物１５が所定数の荷物が入っていない端数の場合にも、個品の総数を算出することができる。 The package baggage tag 14 may include information on the number of individual items in the outer box in the package baggage tag 14 of the package baggage 15. For example, the total number of individual items can be calculated even when the package 15 is a fraction that does not contain a predetermined number of packages.
　（実施形態２）
　実施形態１では、バラ荷物計量部１１は秤である構成としたが、本実施形態では秤ではなく、図４～図８に示すように、撮像部１８である点が実施形態１とは異なる。本実施形態では、実施形態１と異なる点を中心に説明する。 (Embodiment 2)
In the first embodiment, the loose baggage measuring unit 11 is configured to be a scale, but in the present embodiment, it is different from the first embodiment in that it is not a scale but an imaging unit 18 as shown in FIGS. 4 to 8. ..
